Mining in France is based solely on the nature of the material, whether extracted from the surface or underground. These include fuels (coal, hydrocarbons, gas), metals (iron, copper) and a few other minerals (salt, sulfur). The inventory of mining resources is relatively well known for surface and subsurface deposits.
The Union Sulphur Company was incorporated in 1896 to utilize the process. However, the high cost of fuel needed to heat the water made the process uneconomic until the 1901 discovery of the Spindletop oil field in Texas provided cheap fuel oil to the region. [6] The Frasch process began economic production at Sulphur Mines, Louisiana in 1903. [3]
The Nord-Pas-de-Calais Mining Basin is a mining basin in Northern France that stretches across the Nord and Pas-de-Calais departments. The region is famous for its long history of coal extraction and its testimony to a significant period in the history of industrialisation in Europe, and as a result it was inscribed on the UNESCO World Heritage List in 2012.

The Paris area was a relatively flat sea-bottom during the early Cretaceous period: first in a deep-sea environment, then under a more agitated near-shoreline sea towards the end of the same period, Paris's largely silica-based sedimentary deposits became, under the action of pressure and the carbonic acid content of seawater, a thick deposit ...
The Sicilian method was one of the first ways to extract sulfur from underground deposits. It was the only industrial method of recovering sulfur from elemental deposits until replaced by the Frasch process. [1] Most of the world's sulfur was obtained this way until the late 19th century. [2]
Sulfur deposits on a steam vent at Seltún Hot Springs. The hot springs area contains solfataras, bubbling mud pools, fumaroles, hot springs and warm springs. The high sulphur content of the springs give them a characteristic yellow-orange color. Sulfur was mined at this location until the 1880s.

In 2020, oil reserves in France were equivalent to 1% of its annual consumption. [1] These reserves in the geological sense (extractable oil present in deposits) should not be confused with the strategic reserves of three months' full consumption, which can be used in the event of a serious international crisis.
